Problem Page Recorded here are the germination times (in days) for eighteen randomly chosen seeds of a new type of bean: 19, 22, 20, 20, 10, 15, 11, 13, 20, 12, 17, 19, 18, 12, 22, 22, 17, 10 Assuming that germination times are normally distributed, find a 90 % confidence interval for the mean germination time for all beans of this type. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)

What is the lower limit of the confidence interval?

What is the upper limit of the confidence interval?

Problem Page A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 14 days yields the following return percentages: 0.89, -0.27, -2.76, 0.08, 2.29, 2.92, -0.21, -2.69, -2.46, 2.19, -1.58, 1.76, -1.77, 2.57 If we assume that the returns are normally distributed, find a 95 % confidence interval for the mean daily return on this stock. Then complete the table below. Carry your intermediate computations to at least three decimal places....

The U.S. Federal Seed Act establishes germination rates for various fruit and vegetable seeds. Watermelon seeds are to meet a 70% germination standard. A skeptical gardener who has not had very good luck planting watermelons believes that the seed company he purchases seeds from is not adhering to the 70% federal mandate. Once a week for 12 weeks, he purchases a pack of 10 watermelon seeds to act as his sample. He plants the seeds in a greenhouse with good...

Problem Page A researcher wants to estimate the proportion of depressed individuals taking a new anti-depressant drug who find relief. A random sample of 250 individuals who had been taking the drug is questioned; 207 of them found relief from depression. Based upon this, compute a 90 % confidence interval for the proportion of all depressed individuals taking the drug who find relief. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your...

A random sample of 18 health maintenance organizations (HMOs) was selected. For each HMO, the co-payment (in dollars) for a doctor's office visit was recorded. The results are as follows: 10, 11, 6, 12, 8, 10, 10, 6, 11, 7, 9, 9, 12, 7, 8, 11, 8, 12 Under the assumption that co-payment amounts are normally distributed, find a confidence interval for the mean co-payment amount in dollars. Then complete the table below. Carry your intermediate computations to at least...

estion Lifetimes of AAA batteries are approximately normally distributed. A manufacturer wants to estimate the standard deviation of the lifetime of the AAA batteries it produces. A random sample of 17 AAA batteries produced by this manufacturer lasted a mean of 9.4 hours with a standard deviation of 2.2 hours. Find a 99% confidence interval for the population standard deviation of the lifetimes of AAA batteries produced by the manufacturer. Then complete the table below. Carry your intermediate computations to...

The human resources department of a consulting firm gives a standard creativity test to a randomly selected group of new hires every year. This year, 65 new hires took the test and scored a mean of 112.9 points with a standard deviation of 16.5. Last year, 60 new hires took the test and scored a mean of 117.1 points with a standard deviation of 19.2. Assume that the population standard deviations of the test scores of all new hires in...
